Bending of Beams
GATE 2018
Easy
The minimum axial compressive load, P, required to initiate buckling for a pinned-pinned slender column with bending stiffness EI and length L is
- AP = π²EI/4L²
- P = π²EI/L²
- CP = 3π²EI/4L²
- DP = 4π²EI/L²
Explanation
For a column pinned at both ends (effective length Le=L), Euler's critical buckling load is Pcr = π²EI/L².
